摘要
基于传统技术指数的经济分析会为桉树项目决策支持带来复杂性和不明确性,针对这一问题,本文提出了经济综合指数这一解决方法。通过对项目的投资、利润和时效属性的综合,创建了项目营利指数和时间指数,并将经济综合指数定义为二者的加权平均数,权重的设置由项目营利指数和时间指数间的数学关系决定。应用该经济综合指数对广西维都、玉芝树和三门江林场桉树项目进行择优,对福建省永安林业集团工业原料林项目的经营方案进行设计,以及对三门江林场桉树项目进行敏感性分析时所得到的3组结果,与事实和已有研究结论吻合,且过程简捷,计算高效,结论明确。因此,经济综合指数是当前森林经营项目经济效益分析方法的补充。
Aiming at complexity and ambiguity in the economy analysis with traditional technical indices in DSS for eucalypt,an Economic Integrated Index is proposed as a solution in this study.A Project Profit Index and a Project Time Index are created by synthesizing attributes of projects such as investment,profits and efficiency.The Economic Integrated Index is defined as the weighted mean of the Project Profit and Project Time Indices.The weighted average value is determined mathematically, indicating the relationship of the above two indices.We tested the integrated index by choosing an optimum project among the projects of the Weidu,Yuzhishu and Sanmenjiang forest farms and designed a management plan for a project of an industrial raw material eucalypt forest of the Yong＇an Forest Group,Fujian Province.Sensitivity analysis of the Sanmenjiang forest farm project indicated that results produced by the new indices could match the facts and existing conditions very well,with the advantage of simplicity, efficiency and disambiguaty.The Economic Integrated Index is a supplement to existing economic analyses for project of forest management.
